OF SAME PLACE.
IMPROVEMENT IN DEVICES FOR CHANGING THE SPEED OF MACHI Specification forming part of Letters Patent No. 144,499, dated November 11, 1873; application filed October 23, 1873. d
To all whom it may concern:
Be it known that I, ALFRED BETTs, of Wilmington, in the county of New Castle and State of Delaware, have invented a new and Improved Device for Changing the Speed of Machinery; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, in which Figure 1 is a longitudinal vertical section. Fig. 2 is a cross-section in line as w of Fig. 1.
The invention will first be described in connection with all that is necessary to a full understanding thereof, and then pointed out in the claim.
A represents the head-stock of a lathe-boring mill-drill, or other machine in whose upright bearings is journaled a spindle, B. To
this spindle iskeyed a notched'disk, G 0, upon a stud projecting from which is journaled an idler-pinion, D G is theusual pulley or wheel, loosely fitted upon the spindle B, and having attached to the inner end of its hub a pinion, e, which meshes into the idler-pinion D. His a stop, having a screw shank, it, that protrudes through and is adjustable in a slot, f, of the internal gear-wheel, said stopbeing provided with a thumb-nut to fasten it at its points of adjustment.
By movingthe stopH into anotch, c, of the disk 0, the said disk and spindle and internal gear-wheel F are locked securely together and must turn synchronously, a maximum of speed being generated with a given pulley and power.
On the other hand, if the stop is removed from the notched disk and into the notch of projec-
